- Brief Summary
Cesarean section (CS) is one of the most frequently performed surgical procedures in the World. Moderate to severe postoperative pain occurs in a significant proportion of women after cesarean surgery.
Modified Perichondral Approach Thoracoabdominal Nerve (M-TAPA) block performed with ultrasound (US) is a novel technique that provides effective analgesia in the anterior and lateral thoracoabdominal areas, where local anesthetic is applied only to the lower side of the perichondral surface. M-TAPA block is a good alternative for analgesia of the upper dermatome levels and the abdominal lateral Wall, provides analgesia in the abdominal area at the T5-T11 level.
The aim of this study is to evaluate the effectiveness of US-guided M-TAPA block for postoperative analgesia management after cesarean section.
- Detailed Description
Cesarean section (CS) is one of the most frequently performed surgical procedures in the World, in European countries, approximately 20% of deliveries are CS. Moderate to severe postoperative pain occurs in a significant proportion of women after cesarean surgery. This delays recovery and returning to daily life. Postoperative pain disrupts the mother-child bond, makes breastfeeding difficult, and affects the psychological state of the mother. Also inadequate postoperative analgesia may cause hyperalgesia and chronic pain.
Perioperative pain should be managed with a multi-modal approach. Opioids and nonsteroid anti inflammatory drugs should be considered as components of a multimodal analgesic regimen. However, use of both systemic and neuraxial opioids may be associated with effects (respiratory depression, nausea, vomiting, sedation, pruritus, hyperalgesia). For this, interfacial blocks may be preffered to provide postoperative analgesia and reduced opioid consumption.
Modified Perichondral Approach Thoracoabdominal Nerve (M-TAPA) block performed with ultrasound (US) is a novel technique that provides effective analgesia in the anterior and lateral thoracoabdominal areas, where local anesthetic is applied only to the lower side of the perichondral surface. M-TAPA block is a good alternative for analgesia of the upper dermatome levels and the abdominal lateral Wall, provides analgesia in the abdominal area at the T5-T11 level. Sonoanatomy is easy to visualize and the spread of local anesthetic can be easily seen under US guidance.
In the literature, there are studies investigating the effectiveness of M-TAPA block for post-operative pain management in bariatric surgery. However, there is no randomized study evaluating the effectiveness of M-TAPA block for postoperative analgesia management after CS. The aim of this study is to evaluate the effectiveness of US-guided M-TAPA block for postoperative analgesia management after cesarean section. The primary outcome is to compare global recovery scores, the secondary outcome is to compare postoperative pain scores (NRS), to evaluate postoperative rescue analgesic (opioid) use and side effects (allergic reaction, nausea, vomiting) associated with opioid use in this study.

Group Intervention Description Group M-TAPA (Modified Perichondral Approach Thoracoabdominal Nerve block group) Postoperative analgesia management In group M-TAPA, M-TAPA block will be performed with patient is in the supine position. After providing aseptic conditions, the high frequency linear US probe (11-12 MHz, Vivid Q) will be covered with a sterile sheath, and an 80 mm block needle (Braun 360°) will be used. The US probe will be placed in the sagittal plane where the midclavicular line intersects with the costal cartilage corresponding to the costochondral angle. Using the In Plane technique, the probe is gently pushed to visualize the lower part of the costochondral angle at the central level, advancing the block needle in the caudal-cranio direction, 5 ml of saline will be injected into the layer between the transverse abdominal muscle and the lower plane of the costal cartilage, and the block location will be confirmed. After the block location is confirmed, a total of 20 ml + 20 ml of 0.25% bupivacaine(Buvasin %5 flakon) (total 40 ml for both sides) will be injected bilaterally. Group C (Control group) Postoperative analgesia management In the control group, analgesics will be administered according to the protocol in postoperative analgesia management.
- Primary Outcome Measures
Name Time Method Global recovery scoring system (patient satisfaction scale) The quality of recovery will be evaluated out of a total of 150 points according to the QoR-15 test to be applied at the portoperative 24th hour. We will use the Turkish version of Quality of Recovery / QoR-15 questionairre
PART A How have you been feeling in the last 24 hours? (0 to 10, where: 0 = none of the time \[poor\] and 10 = all of the time \[excellent\])
1. Able to breathe easily
2. Been able to enjoy food
3. Feeling rested
4. Have had a good sleep
5. Able to look after personal toilet and hygiene unaided
6. Able to communicate with
7. Getting support from hospital doctors and nurses
8. Able to return to work or usual home activities
9. Feeling comfortable and in control
10. Having a feeling of general well-being
PART B Have you had any of the following in the last 24 hours? (10 to 0, where: 10 = none of the time \[excellent\] and 0 = all of the time \[poor\])
11. Moderate pain
12. Severe pain
13. Nausea or vomiting
14. Feeling worried or anxious
15. Feeling sad or depressed
- Secondary Outcome Measures
Name Time Method Postoperative pain scores (Numerical rating scale) (0-meaning "no pain" to 10-meaning "worst pain imaginable") Patients will be evaluated at the first 24 hours period postoperatively. Postoperative 24 hours period. Patients' pain scores will be questioned at 0, 2, 4, 8, 16 and 24 hours.
The use of rescue analgesia Meperidine consumption will be recorded at the first 24 hours period postoperatively. (Number of Participants and Concentration of Meperidin) The need for rescue analgesia will be recorded at the first 24 hours period postoperatively.
